Organisms Interfaces
  1. The main three
    1. Skin
      1. blood clot forms
        1. prevents pathogens from entering
        2. skin breaks
          1. pathogens enter wound before clot is formed
        3. Gas-Exchange system
          1. Breathe in air containing pathogens
            1. most trapped in the mucus lining of the lung epithelium
              1. Epithelium= the outer layer of cells in the passsages to the lung
                1. These cells have Cilia
                  1. that beat and move the mucus up to the trachea to the mouth
              2. Some pathogens reach aveoli
                1. invade cells and cause damage
            2. Digestive system
              1. most pathogens killed by stomach acid
                1. Some survive stomach acid
                  1. pass into intestines
                    1. invade cells of the gut wall
                      1. Causes disease
              2. Key
                1. Positive
                  1. Negative
